LISTED-CORN CU LTIVATO R SPECIFICATION forming part of Letters Patent N0. 670,5i41, dated March 26, 1901. Application filed July 28, 1900. Serial No. 25,153. (No model.)

To all whom, it may concern.-

Be it kn own' that I, OASSIUS C. KEITH, a citizen of the United States, residing at Bladen, in the county of Webster and State of Nebraska,have invented a newand useful Listed- Corn Cultivator, of which the following is a specification.

My invention is an improved listed-corn cultivator; and it consists in the peculiar construction and combination of devices hereinafter fully set forth, and pointedout in the claim.

In the accompanying drawings, Figure 1 is a perspective view of a listed-corn cultivator embodying my improvements. Fig. 2 is a top plan view of a'single section of the same. Fig. 3 is a vertical longitudinal sectional view of the same. Fig. 4 is a detail sectional view of one of the cultivator-knives.

In the embodiment of my invention I provide cultivator-sections l, which may be used singly to cultivate one row of corn at a time or combined in numbers of two 'or more to cu1-' tivate two or more rows of corn simultaneously. The said sections are alike in construction, and I will now describe one of them.

A pair of runners 2, which are of suitable size, are provided on their inner sides, near their front and rear ends, with vertically-disposed brackets 33, which are provided at their upper ends with horizontallydisposed inwardly-extending arms 4. The said brackets 3 are provided with vertical adjusting-slots 5, and bolts 6, which secure the said brackets to the said runners, operate in the said slots, and thereby the said brackets may be adjusted vertically with relation to the runners, as will be understood. A cross-bar 7 is bolted on the arms 4 of brackets 3 near the front ends of the runners and, together with the said brackets, connects the said runners together. The

said cross-bar '7 is provided with adjusting.

openings 8 for the bolts 9, whereby the front ends of the runners may be laterally adjusted to widen or narrow the space between them. A cross-bar 1O,whicl1 is similar in construction to the cross-bar 7, but is longer than the latter, connects the brackets 3 at the rear ends of the runners: The said cross-bar I0 is 'provided with a series of adjusting-openings 11 for the bolt 12, which secures the same to the arms of the said bracket to admit of the lateral adjustment of the rear ends of the runners, and the end portions of the said crossbar 10, which extend beyond the rear brackets 3 and beyond the outer sides of the runners 2, are provided with adjustingopenings 13. Longitudinally-disposed bars let connect the cross-bars 7 and are bolted thereto, as shown. Said bars 14 are provided on their upper sides, neartheir rear ends,with keepers 15, in the lower sides ofwhich are mounted rollers 16. Where two or more of my cultivator-sections are connected together, as shown in Fig. 2, the connecting-bar 16 is passed through the said keepers and bears on the said rollers 16. Pins 18 in adjustingopenings 19, with which said connecting-bar is provided near its ends, secure the sections 1 to the said connecting-bar at any desired distance apart. The connecting-bar supports the seat 20 for the driver. Beams 21, which are preferably of the form here shown, have their front ends bolted to the extended end portions of the cross-bar 10 by means of bolts 22, which are placed in appropriate adjusting-openings 13. The said beams extend rearward from the cross-bar, and to their downturned rear ends are secured the obliquely-disposed cultivator-knives 23. Said cultivator-knives are preferably of the form here shown and have the horizontal lower cutting edges 24 and the inclined front cutting edges 25, said cutting edges 24 25 being sharpened and converging to a point at the front of each knife. The said knives are concaved on their inner faces 26, as shown,

and the same, owing to the oblique disposition thereof on their respective supporting'-' beams, operate in rear of the runners -2, and the beams 21 being adjustable on the crossbar 10 said cultivator-knives maybe spaced to any desired distance apart.

The sharp points at the front ends of the knives prevent them from clogging the stubhis or other trash and enable them to readily cut through the soil. When the machine is in operation, the runners travel in the furrow, one on each side of the rowof plants, the front ends of the knives out the soil from each side of the furrow, and the said knives owing to the oblique disposition thereof serve to push the soil to the center of the furrow. The lower edges of the knives being sharp tached to said cross-bars, the longitudinallydisposed bars connecting said cross-bars, the beams adjustably secured to the rear cross bar and the cultivating-knives carried by the said beams, said cultivator-knives being obliquely disposed with relation to the runners and in rear thereof,substantiallyas described. In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses;
